doc: fix conan version in DEVELOPMENT.md

[ashkrisk]

The conan version used in all the setup scripts was updated to 1.61.0 in #27870. However, a line in the developer documentation was left out.

Since the dependencies no longer install correctly with conan 1.58 (#27869), all documentation should consistently use the updated version.
